Description

The TPSI31Px-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of the TPSI31Px-Q1 device family in an electric vehicle (EV) or hybrid electric vehicle (HEV) high-side active precharge application for charging a DC-link capacitor. The board features the TPSI31P1-Q1, an isolated switch driver with integrated 15.8V gate supply and comparators to monitor charging current and hysteretically drive the gate, completely on the secondary side with no additional logic needed. The EVM also has the TPSI3052-Q1, an isolated switch driver with integrated 15V gate supply, acting as an isolated power supply to help provide additional switching power to the TPSI31P1-Q1 if needed. The EVM features a buck topology with two HV inductors (each rated for 400V). The EVM also includes an N-Channel 1200V 18A silicon carbide (SiC) MOSFET in a TO-263-7L package. The board contains multiple test points to monitor TPSI31P1-Q1 functionality. In addition, the EVM contains an adjustable 5V LDO to support battery powering.
